Choose whether the shutter-release button can be used to
focus. If [
AF-ON only ] is selected, the camera will not focus
when the shutter-release button is pressed halfway. Focus can
only be adjusted using the
AF-ON button or other controls to
which AF-ON has been assigned using Custom Setting f3
[
Custom controls ].
Choose whether focus-point selection “wraps around” from one
edge of the display to another.
If [
Wrap ] is selected, focus-point selection will “wrap around”
from top to bottom, bottom to top, right to left, and left to right,
so that, for example, pressing
2 when a focus point at the right
edge of the viewfinder display is highlighted selects the
corresponding focus point at the left edge of the display.
